Anti-PAR2 (Proteinase Activated Receptor 2)

Proteinase-Activated Receptor 2 (PAR-2) is a proteinase activated 7-transmembrane G-protein-coupled receptor. Human PAR-2 contains a cleavage site for trypsin, mast cell tryptase or coagulation factor VIIa or Xa, 11 amino acids (aa) C-terminal to the signal sequence. Cleavage creates a tethered ligand that activates the 361aa receptor. PAR-2 is expressed in kidney, pancreas, stomach, intestine, airway, skin, bladder and brain, activation stimulates release of inflammatory and nociceptive mediators. PAR-2 is downregulated by ubiquination, endocytosis and degradation. Mature human PAR-2 shows 78% amino acid identity with mouse PAR-2 over the extracellular portions.
